I mean, I really want subs in my vehicle, but the CRV is a small SUV. I need the use of cargo room, I play hockey and need room for all my equipment and I also fish and do other stuff that would limit my space.

Would it be terrible to put 2 subs in the rear door panels and then dynamat the doors?

Would I be loosing quality by running 2 speakers up front and 2 subs in the back?
